Hi,

I want to force NIC speed in 100FD on bge nic.

I know how to do this on eri and qfe, but same commands didn't work for bge.

Example:

<a href="mailto:ROOT&#64;drfw2" target="_blank">ROOT@drfw2</a> $ ndd -set /dev/eri instance 0

<a href="mailto:ROOT&#64;drfw2" target="_blank">ROOT@drfw2</a> $ ndd -get /dev/eri link_speed

1

<a href="mailto:ROOT&#64;drfw2" target="_blank">ROOT@drfw2</a> $ ndd -get /dev/eri link_mode

1

on bge:

<a href="mailto:ROOT&#64;drfw3" target="_blank">ROOT@drfw3</a> $ ndd -set /dev/bge instance 0

operation failed: Invalid argument

<a href="mailto:ROOT&#64;drfw3" target="_blank">ROOT@drfw3</a> $ ndd /dev/bge \?

operation failed: Invalid argument

<a href="mailto:ROOT&#64;drfw3" target="_blank">ROOT@drfw3</a> $ ls -las /dev/bge

2 lrwxrwxrwx1 rootroot 29 Sep 27 11:45 /dev/bge -> ../devices/pseudo/<a href="mailto:clone&#64;0" target="_blank">clone@0</a>:bge

Any idea?

Thanks,

Tarek

You need to create a bge.conf file and place it in /platform/sun4u/kerne/drv. I don't remember the syntax off the top of my head, but you can look it up @sunsolve.sun.com

I will tell you, the bge interface does a much better job at auto-configure that the old hme's, qfe's, eri's ever did, plus, of you force the bge to a speed different from the one at the switch, you will not get a network connection. I am replacing a whole bunch of 1120s with v240s, and the auto-neg bfe's work great.

I'd recommend just leaving it as it is.
